Email

Scrambles the characters in an email address. It preserves formatting and keeps the @ and . characters.

For example, for the following input value:

[e-mail]

The output value would be something like:

[e-mail]

By default, the generator scrambles the domain. You can configure the generator to not mask specific domains. You can also specify a domain to use for all of the output email addresses.

For example, if you configure the generator to not scramble the domain company.com, then the output for [e-mail] would look something like:

[e-mail]

This generator securely masks letters and numbers. There is no way to recover the original data.

If your email addresses include name values - for example, [e-mail] - then you can use the Regex Mask generator to produce email addresses that are tied to name values in the same table. For information on how to do this, go to Aligning email addresses to names.

How to configure

To configure the generator:

1. In the Email Domain field, enter a domain to use for all of the output values. For example, use @mycompany.com for all of the generated values. The generator scrambles the content before the @.

2. In the Excluded Email Domains field, enter a comma-separated list of domains for which email addresses are not masked in the output values. This allows you, for example, to maintain internal or testing email addresses that are not considered sensitive.

3. Toggle the Replace invalid emails setting to indicate whether to replace an invalid email address with a generated valid email address. By default, invalid email addresses are not replaced. In the replacement values, the username is generated. If you specify a value for Email Domain, then the email addresses use that domain. Otherwise, the domain is generated.

4. Toggle the Consistency setting to indicate whether to make the column self-consistent. By default, consistency is disabled.
